Some said it couldn't be done.

They may have been onto something.
It struck an arc easy when I touched the electrode to the workpiece, but it would immediately go out. I think my software was limiting the current too much and too soon. Not sure what caused the catastrophic failure, but my emitter follower makeshift 12v regulator blew, one of the FETs popped and the bypass cap lead appears to have turned itself into a fuse. The batteries (6s SPIM08HP) seem to have handled it no problem but I'm not sure I would recommend these batteries because they're a pain to wire up.
